This invention relates to an insect shield for doors, and more particularly to a screen door so designed as to reduce the tendency of insects to enter a building when the door is open.

A primary object of this invention is the provision of an improved screen door having an auxiliary section associated therewith, and simultaneously openable with the 'door, designed to prevent the direct passage of insects through the door when the same is open.

A further object is the provision of such a door as set out in the foregoing object, of improved means for opening the doors simultaneously.

A still further object is the provision of a screen door of improved insect resistant design.

Still further objects will in part be obvious and in part be pointed out as the description of the invention proceeds and shown in the accompanying drawing, wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawing:

Figure 1 is a. front elevational view of one form of screen door embodying this inventive concept.

Figure 2 is a top elevational view of the door shown in Figure 1.

Figure 3 is a fragmentary side elevational View showing certain details of construction, and

Figure 4 is a sectional view taken substantially along the line 4-4 of Figure 1, as viewed in the direction indicated by the arrows.

Like reference numerals refer to like parts throughout the several views of the drawing.

Having reference now to the drawing, a door frame H] of conventional design set in any desired location in a building, has secured thereto as by hinges II a screen door including a frame I2 havin apertures therein and screening l3 in the apertures. Door I2 is adapted to close a substantial area of door frame ill, but not the entire space surrounded by the door frame. A second supplemental screen door i3 is hinged as by hinges l4 to the opposite side of the door frame, door l3 in conjunction with door l2 being adapted to completely clOse the door frame. A suitable handle I5 is provided On door l2 to facilitate opening of the same.

It is to be noted that the doors open outwardly in opposite directions due to the fact that the hinges l4 and H are set on opposite sides of the frame.

Means are provided whereby when door I2 is opened, door [3 simultaneously opens. Such means take the form of a bracket I6 secured to the upper portion of the frame of door l2, and provided with a lug I7 extending upwardly above 5 Claims. (01. 160-48) the upper extremity of the door to which is secured, as by means of an adjustable nut and bolt connection iii, a cord I9. Cord it! extends to and around a pulley 20 secured to door frame ID at a point above and adjacent door [3 and thence extends forwardly to a bracket 2| secured to and extending outwardly from door I3, being secured to the upper frame thereof.

As best shown in Figure 2, suitable springs of conventional type 23, and 24, are secured to the door frame and doors l2 and [3, respectively, to provide for their return to closed position after they are opened.

From the foregoing it will now be readily apparent that as door I2 is opened, either by pressure from the inside of the building, or by the operation of handle l5, cord l9 will act about pulley 20, on bracket 2| to simultaneously open door l3, thus providin an adequate space for the passage of persons to and from the building. However, as the door [2 is opened outwardly insects and so forth on the wall of the building adjacent the door will not be driven inwardly through the door by the passage of the body of a person therethrough but will be blocked and deflected by the partially opened door segment l3, which will turn them from their course into the interior of the building and guide them along the outside wall.

From the foregoing it will now be seen that there is herein provided an improved screen door which accomplishes all the objects of this invention and others including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

1. An insect excluding screen door comprising a door frame including a pair of jambs, a screen door hinged to a first jamb and extending partially to the second jamb, a screen insect bafile hinged vertically to said second jamb and being complementary with said screen door to selectively close the door frame and means connecting said door and said baflle for causing opening of said baffle upon opening movement of said door.

2. An insect excluding screen door comprising a door frame including a pair of jambs, a screen door hinged to a first jamb and extending partially to a second jamb, a screen insect bafile hinged vertically to said second jamb and being complementary with said screen door to selectively close the door frame and means connecting said door and said baffle for causing opening of said baffle upon opening movement of said door, said bafile having an outwardly pivoting movement for sweeping away insects as said door isvoppnedr.

3. The combmatiom of claim:1);;sa-id;;means comprising an arm on said door and an arm on said bafiie, and a flexible cable having one .end. secured to said arm on said door and the other secured to said arm on said bafii'caand agjpuliey;

secured to said frame and guiding said cable intermediate its ends.

4. The combination of claimg3, said'means be ing disposed outside and above said doorway to permit freely opening said door and said-bafiie without hindrance from said means.

means including a screw threaded fastener on said cable engageable with said door for attaching said cable to said door.
